How does a methanol fuel cell work?

Direct Methanol Fuel Cell (DMFC) is one of the proton exchange membrane fuel cells (PEMFC), which uses methanol aqueous solution or steam methanol directly as a fuel supply source without the need for methanol, gasoline and natural gas reforming. Hydrogen is produced for power generation. Compared with proton exchange membrane fuel cells (PEMFC), direct methanol fuel cells (DMFC) have the characteristics of low temperature fast start, clean fuel and environmental protection, and simple battery structure. This makes direct methanol fuel cells (DMFC) a mainstream for future portable electronics applications.

A direct methanol fuel cell is a variant of a proton exchange membrane fuel cell that uses methanol directly without prior reforming. Methanol is converted to carbon dioxide, protons and electrons at the anode. Like a standard proton exchange membrane fuel cell, protons react with oxygen at the cathode through a proton exchange membrane, and electrons pass through an external circuit to the cathode and work.

Basic conditions Total reaction formula: 2CH4O + 3O2 + 4OH-= 2CO32- + 6H2O

Positive electrode: 3O2 + 12e– + 6H20 → 12OH–

Negative electrode: 2CH4O - 12e– + 16OH~ → 2CO32- + 12H2O

Acidic condition CH4 + 2O2 → CO2+2H2O

Positive: 3O2 + 12e– + 12H+ → 6H2O

Negative electrode: 2CH4O - 12e– + 2H2O → 12H+ + 2CO2

The battery has a desired operating temperature of 120 ° C or less, which is slightly higher than a standard proton exchange membrane fuel cell, and its efficiency is about 40%.

A direct methanol fuel cell is a variant of a proton exchange membrane fuel cell that uses methanol directly without prior reforming. Methanol is converted to carbon dioxide and hydrogen at the anode, and like a standard proton exchange membrane fuel cell, hydrogen is then reacted with oxygen.
